Birth Rate Incentives

The Jornal de Negócios today stated that the Government has announced that single-parent families will get 20% more family allowance, as an incentive to increase the birth rate.

I was somewhat puzzled by this. Are they implying that women will have more children and then split up with the father in order to get more cash from the State? Doesn't that bring social problems that will weigh on the State budget? Or are they proposing Michael Jackson type surrogate mother arrangements to encourage single fathers?

Somebody's done their sums wrong, it would appear...
